DXair is the only company offering an approved Energy Star rated open or closed loop geothermal dehumidification system from 2 thru 6 ton.

DXair-G-LR utilizes a standard Energy Star rated reverse cycle geothermal unit applicable for open and close loop applications. The packaged base unit comes standard with two speed compressor, evaporator, and liquid to refrigerant coaxial condenser/evaporator, ECM blower motor and de-superheater. This unit operates as a typical geothermal heat pump for space heating and cooling with the de-superheater in play.

For space dehumidification, a liquid reheat coil is field installed as is the MAXevap option without disturbing the base unit to negate the Energy Star rating. In the DH (dehumidification) mode, the system is in the cooling mode absorbing the latent and sensible heat and rejecting to the liquid reheat coil on the supply. In this mode, the solenoid valve or loop pump is de-energized and the unit operates as a standalone dehumidifier. The external MAXevap is energized maintaining a 33F evaporator temperature while the unit rejects 100% of the sensible, latent and compressor heat to the space.

Pool heat recovery is accomplished utilizing cupro-nickel double walled vented de-superheater. Electric built in duct heaters, hot water coils, etc. are available for second stage space heating.

DXair-G-HGR is a non- Energy Star rated reverse cycle, geothermal unit applicable for open and close loop applications. The packaged base unit comes standard with compressor, evaporator, 100% hot gas reheat condenser, liquid to refrigerant coaxial condenser/evaporator, MAXevap option and air handler. This unit operates as a typical geothermal heat pump in heating and cooling. In the DH (dehumidification) mode, the coaxial condenser/evaporator is not in play and the solenoid valve or loop pump is de-energized. The unit is now operates as a standalone dehumidifier with the MAXevap energized maintaining a 33F evaporator temperature while the unit rejects 100% of the sensible, latent and compressor heat to the space.

Options

There are three pool heat recovery options. They all include cupro-nickel double walled vented heat exchangers.

• Option 1 is a standard de-superheater capable of rejecting 15-20% of system capacity in all modes.
• Option 2 is a larger condenser capable of rejection 50% of the unit’s capacity in the DH mode.
• Option 3 is a dedicated condenser capable of heating the pool water utilizing 100% of the system’s capacity on demand.  

Electric built in duct heaters are available for second stage space heating.
